More Information
Summary:Active control of light emitting diodes (LEDs) and LED packages within LED displays is disclosed. LED packages are disclosed that include a plurality of LED chips that form at least one LED pixel for an LED display or an LED panel. Each LED package may include an active electrical element that is configured to receive a control signal and actively maintain an operating state, such as brightness or grey level while other LED packages are being addressed. Active electrical elements are disclosed that are configured to provide both forward and reverse bias states to LEDs to detect adverse operating conditions including reverse leakage and deviations to forward voltage levels. LED packages are also disclosed that may self-configure based on the manner in which various input or output lines are connected.
